I attach a GIF picture as test case.

Reproducible: Always

Steps to Reproduce:

Bug confirmed in KDE 4.5.0.

It works in KDE 4.4.5 :-(

Comment 2 gianted 2010-09-07 21:26:47 UTC

I'm facing it also with Dolphin 1.5, KDE 4.5.1.

Comment 3 Janet 2011-01-15 15:30:26 UTC

I think this is "invalid". 

For all my "transparent" GIFs I have previews in dolphin in KDE 4.4.x and 4.5.x.

But I have to admit for that cute little fox I don't get a preview when saved to disk. BUT when you look at the picture with a hex-editor you'll notice that this file indeed isn't a GIF, it's a PNG! Rename it and you'll get the preview!

Comment 4 Janet 2011-01-15 15:34:17 UTC

I have had this with files too that were named as .jpg but actually were PNGs. And I think dolphin is right to not show the preview of those files because that's a hint for the user that there is something wrong - in that case the file classification - so that it can be corrected.

Comment 5 Peter Paulsen 2011-01-15 15:37:09 UTC

I think dolphin should show the previews for those wrong named files nonetheless. But it should also show a clear warning in the tooltip information that the filetype is wrong.

I think this report and bug 220496 are talking about the same problem. Also see see bug 182361.

Comment 8 gianted 2012-01-01 14:05:13 UTC

I don't know if i made the correct action... I put this bug as closed, because 1.7 - KDE 4.7.4 now the issue seems to be fixed.
